FBMC/OQAM Transceiver for Ultralarge Bandwidths

Abstract

We consider the problem of the downlink transceiver design when it needs to operate in an ultralarge analog bandwidth; more specifically, we propose to use the FBMC/OQAM system in a scenario where many other multicarrier transceivers are not able to operate. For such a case, we consider the problems of the equalizer implementation and of the design of its coefficients, and we define proper procedures for solving them by resorting to the MMSE approach. The simulation results show the capability of the proposed solutions to operate also on the most hostile wireless channels at the price of a reasonable increase of the receiver computational complexity.
